  • What is poly aluminum-ferric chloride (PAFC)?
  • See Materials (Basel). 2025 April 25; 15 (9): 3104. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.
  • Is polyaluminium ferric chloride a composite coagulant?
  • Gao B., Yue Q., Miao J. Evaluation of polyaluminium ferric chloride (PAFC) as a composite coagulant for water and wastewater treatment. Water Sci. Technol. 2003;47:127. doi: 10.2166/wst.2003.0033. [ PubMed] [ CrossRef] [ Google Scholar] 16.
  • What is PAFC from coal gangue?
  • The XRD and FT-IR spectra showed that the prepared product is a mixture of PAFC with different degrees of polymerization. The preparation of PAFC from coal gangue can realize the resource utilization of gangue. It is mainly used for the treatment of coal industrial wastewater and the treated water can be recycled.
  • How is PAFC synthesized?
  • PAFC was synthesized following two steps: First, 50 g of blast furnace dust was placed in a 500 mL three-necked round bottom flask equipped with stirrer and reflux device. Then, 2 g NaF, 150 mL of HCl diluted solution (36%, freshly diluted 1:1 with ultrapure water) and 5 mL of HNO 3 were added.
